This commit adds support for a NOT_EQUALS operator to the management
operations which already support filtering.
It also adds a handful of tests for the predicate since there didn't
seem to be any such tests.
When a bytes property is added to an AMQPMessage and it is then reencoded it
will fail without first wrapping the byte array in an AMQP binary as required
by the ApplicationProperties section specification defined type allowances.
There was already some verification at AMQPMirrorControllerSource::invalidTarget
however the verification failed on soak test ReplicatedBothNodesMirrorTest,
and an user I was working with also gave me evidence of this happening.
I'm improving the previous verification, which is actually a simplification that works on every case.
When converting a large server message to an outgoing STOMP frame the converter
is allowing unsafe concurrent access to the large message internals which leads
to failures on message deliver as the state is out of sync amongst the dispatch
threads.
Throwing an exception when clearing the bindings when a
cluster-connection is closed short-circuits the clearing (and closing)
process. This commit fixes that by simply logging the failure to clear
and continues on.
No new tests are added with this commit. It relies on existing tests.
PriorityLinkedList has multiple sub-lists, before this commit PriorityLinkedList::setNodeStore would set the same node store between all the lists.
When a removeWithID was called for an item on list[0] the remove from list[4] would always succeed first. This operation would work correctly most of the time except
when tail and head is being used. Many NullPointerExceptions would be seen while iterating on the list for remove operations, and the navigation would be completely broken.
A test was added to PriorityLinkedListTest to make sure the correct lists were used however I was not able to reproduce the NPE condition in that test.
AccumulatedInPageSoakTest reproduced the exact condition for the NPE when significant load is used.
We've traditionally used org.apache.activemq.artemis.utils.Base64 for
Base64 encoding/decoding. This implementation is based on public domain
code from http://iharder.net/base64.
In Java 8 java.util.Base64 was introduced. I assumed we hadn't switched
to this implementation for performance reasons so I created a simple
JMH-based test to compare the two implementations and it appears to me
that java.util.Base64 is significantly faster than our current
implementation. Using the JDK's class will simplify our code and
improve performance. Also, it should be 100% backwards compatible
since Base64 encoding/decoding is standardized.
When an AMQP message is sent over a cluster bridge it is embedded into a
Core message. If the size of the AMQP message is barely beneath the
minLargeMessageSize then the Core message in which the AMQP message is
embedded will become a large message. The on the bridge target when the
embedded AMQP message is extracted from the large Core message it will
not be considered "large." In this situation the file for the large Core
message will leak.
Thanks to Erwin Dondorp for the test. I renamed and refactored it a bit,
but the fundamentals came from Erwin.
For embedded use-cases the Micrometer MeterRegistry may be passed in
from the application and used for other meters unrelated to the broker.
Therefore, the broker should not change the config of the MeterRegistry
(e.g. by adding common tags to all meters) as the config change(s) may
be incompatible with the needs of the embedding application.
The class org.apache.activemq.artemis.core.protocol.openwire.OpenWireConnection in ActiveMQ Artemis
is based on org.apache.activemq.broker.TransportConnection from ActiveMQ Classic,
and in the latter there is null check that doesn't exist in the former.
Therefore, I think it's worth adding this check.
The info should never be null since it is passed in off the wire from the OpenWire marshaller,
and state.getSessionIds() should also never return null because the underlying ConcurrentMap is initialized when ConnectionState is created.
